The equation 2Cr2O3 + 3No -> 4CrNoO3.

1. The chemical equation 2Cr₂O₃ + 3No -> 4CrNoO₃representsthechemicalreactionprocessbetweenChromiumtrioxide(Cr₂O₃)andNitricoxide(NO)toproduceNitratechromium(CrNoO₃).

2. Reaction condition: This reaction requires the presence of high temperature or light to facilitate the process.

3. Reaction process: When Chromium trioxide and Nitric oxide come into contact with each other under suitable reaction conditions, they combine to form Nitrate chromium.

4. Occurring phenomena: A color change can be observed in this reaction process, but specifically it will depend on the concentration of the reacting substances.

Note: The above chemical equation may not be accurate as CrNoO₃ is not a known chemical compound. This equation might be hypothetical and used for the purpose of teaching experimental chemistry.
